ECS with 2-stage water separation

摘要

A two spool environmental control system includes a low pressure spool subsystem comprising a low pressure turbine and a condenser downstream of the low pressure turbine. A high pressure spool subsystem is in air flow communication with the low pressure spool subsystem and includes the condenser, a first water extractor in air communication with the condenser, a high pressure turbine downstream of the condenser, a second water extractor in air flow communication with the condenser, and a reheater downstream of the high pressure turbine.
